TECHNICAL DATA SHEET - 1.8523

Material category: 3.2Cr - 0.95Mo - 0.2V base carburized steel

Product description
1.8523 is usually produced by EAF /VD /LF followed by electroslag refining (ESR) if necessary for special purpose. Bars and, where applicable, forgings are subjected to ultrasonic examination based on the different level according to the buyers' requirements.
Bar are usually supplied bright in the annealed condition.
Final heat treatment - quenched and tempered.
